Beit known that I, RAY H. MANsN citi zen of the United States', residing :it ria, 'in the county of Lorain and State of hio', have invented e certain new and useullmprovement in Telephone Desk Sets, of which the following is a full, clear7 concise, und

this specification.

My linvention relates to telephone desk sets und contemplates 'new features Voi construcan instrument wh tion und arrangement which have particu-V larly to do with the design. of the outer and apparatus supportxngparte to produce 1c is very substantial und v-naetically unbreakable, at the same time facture.

- My invention may' be'considered as roven'ientover' the inventionshown in my. intent No.- 829,410,. dated August 28, 1906.

In-thedeskset o'f this patent and in others more or less trouble isencountered, due to ythe lcemng and separation of the various parte. Iii-these instruments also mostof the parteci-e cnstin the Abreaka of which has given considera le trouble anI annoyance as avoided by punching the .various parts freni welles causing an increase in maintenance; In some de'sk sets this breakage `hes 4been sheet metal.; jbut the change from castingsto sheet metal unchings does not -oy'ercome the A trouble-res ting from loosening and se m- Ation of theperts. A

great deal-o this .-trouble occurs where the transmitter shellis secured to the base piece supported from the -capor headieee of the standard. 'I overcome all of 'rese diiiculties bypnnching all the parts from sheet metal, by. makingthe back of th.' trensmitte and the hinged goint 4or su )porting base-from one piece-of metal,

Upon assembly, the supporting strip is inserted into the tube from 4the top, and the lower end of the lookin spring 23 will sli o ver the top of the loc g tooth 25 until said tooth enters the locking slot 24, thus lookin the supporting strip against vertical upwar displacement. When the cap frame is now brought into osition over the end of the tube and over t e projecting. t end of the su porting strip. and the loc pin 22 appli the supporting framewill se. curey loclrcd into osition, and the ca frame will 'also be ocked a ainst vertice and rotational displacement. he upper end of the front wall 26 of the neck art 17 'of the ca frame has al slot 27 whi 'registers with e channel between Athe side walls 15 and 16 of the supporting Thron h the side walls 15.an 16 are e openings an through the side walls of the nec part 17 and in register with the openings 28 are the openings 29. These openings, as 'will be described later, are for the reception of the ivot bolt for supporting the transmitter menand vthe s1ot2 odors an outlet for the,-

transmitter, leads which extend into and through the cap frame and standard tube to connect with tlie'contact plates 30 and 31`se cured to the lower end of the su port' strip, being insulated therefrom an exten i into the base of the standard fra-me.

n the instrument in the patent referred to and also in other desk 'sets on the market, the transmitter frame is secured to the snpxporting base which is-hinged to the cap me, but iny laccordance with my invention the transmitter frame, the supporting plate, and the hinged .mechanism are comprised in a unitar structurestamped from sheet material, 's unitaic' structure comprises the bod' part 32 whi forms the re'ai" inclosir she of the transmitter frame 33, the meta beiner drawn out au? rhis hin saffmme in -iis itlwer will' ha e o in or receivm e upper en gli thgp the side wl of thehinged J ame avm e o in or erin g 428 im 2%,sthe's of thi Planein to form the hinged frame wthtoglxilshgis thro h all f th ivo 4 assmg u o y ese s toseciirethetransmiter shell to the end of e cap frame.
